Title: Optical wind direction sensor
Inventor: UNNO SHUJI
IPC: G01P13/02
Filed: 1999-09-28
Abstract: PROBLEM TO BE SOLVED: To provide an optical wind direction sensor in which a failure and a malfunction due to lightning are not generated and in which a power supply and a data transmission device are not required. SOLUTION: A perforated rotating plate 2 is turned so as to be interlocked with a wind direction indicator 1. Thereby, optical paths between optical fibers 41, 42, 43 and reflection plates 61, 62, 63 are intermitted. When the intermittency of the optical paths is detected via an optical fiber 40 and the optical fibers 41, 42, 43, a wind direction can be detected. Since light which is propagated through the optical fibers 40, 41, 42, 43 is not influenced by lightning, the failure and the malfunction of this optical wind direction sensor 6 are not geenrated. In addition, a power supply is not required in the optical wind direction sensor 6, and it is not required to install a data transmission device at a photodetector 9.

Abstract: PROBLEM TO BE SOLVED: To attain the increase of the access speed and to attain the miniaturization of a motor by deciding the number of rotation of a disk at the time of reproduction with a detected value of the information recorded area prior to the information reproduction. SOLUTION: The information recorded area on the optical disk 1 is detected by an area detector 9.

Abstract: PROBLEM TO BE SOLVED: To efficiently weld steel plates having a large thickness by invading the tip part of a first electrode into a beveling, successively, invading the tip part of a second electrode into an opening hole side of the beveling and welding. SOLUTION: The tip part of the first electrode T1 is deeply invaded into the bevelings on the steel plates WR to be welded. The tip part of the second electrode T2 is invaded at the position near the opening hole side of the beveling from the tip part of the first electrode T1. A shaking means E shakes the first and the second electrodes in the plate thickness direction of the steel plates WR. A carrier 100 is fitted to a rail L parallel fixed to the surfaces of the steel plates WR, and the first and the second electrodes are shifted in the longitidinal direction of the bevelings on the steel plates WR through the shaking means E. Since the heat is inputted at the deep side and the opening hole side in the beveling part, the temp. distribution is uniformized. Negative welding voltage to the steel plates WR is impressed to the first electrode.  Positive welding voltage is impressed to the second electrode. Arc of the first electrode having straight polarity is good to melting of the bottom part of the beveling. Arc of the second electrode having reversed polarity has high concentration, and the interference between the first and the second electrodes is avoided.

Title: Electrophotographic sensitive body
Inventor: NAKAZAWA SUSUMU
IPC: G03G5/147
Filed: 1987-10-29
Abstract: PURPOSE:To obtain an electrophotographic sensitive body having small residual potential but having stable photosensitive characteristics and electric characteristics after using repeatedly, and resulting high durability by incorporating a binder resin and a surface active agent into a protective layer. CONSTITUTION:A binder resin and a surface active agent are incorporated into a protective layer. Since the protective layer contains the surface active agent, a residual potential is reduced due to a small amt. of the protective film even when the film thickness is made thick. Moreover, the residual potential is reduced with a small amt. of the surface active agent. By this method, the mechanical strength of the protective layer, etc., is not reduced, and stable electrification characteristic and photosensitive characteristics are exhibited even after repetitive use, resulting thus high durability of the electrophotographic sensitive body.

Filed: 1987-10-30
Abstract: PURPOSE:To reduce power consumption and to perform overwrite on a high frequency area by forming a magnetic head by a core formed by a first magnetic material and second magnetic materials laminated via a non-magnetic material on the first magnetic material and a coil wound across the core. CONSTITUTION:A base material 3 on which a large number of magnetic heads 1 are provided is arranged in a direction to cross with the track 11 of a magneto-optical disk 10. By projecting a laser beam from a semiconductor laser on the disk 10 in such state, the magnetic head 1 being positioned on the opposite side of an irradiated disk 10 is selected by a position sensor. And a current flows only on a selected disk 1 and a magnetic field is generated, thereby, the overwrite can be performed. In such a case, it is possible to reduce inductance because the coil 9 is constituted in a thin film. In such a way, it is possible to reduce the power consumption by suppressing a heating quantity on the coil, and to perform the overwrite on the high frequency area by the fact that the leading edge of magnetic field strength can be accelerated.

Title: Flat type vibrating motor
Inventor: SAKASHITA HIROSHI
IPC: H02K7/065
Filed: 1995-10-24
Abstract: PROBLEM TO BE SOLVED: To eliminate the run-out of the rotor of a vibrating motor so that the motor can generate vibrations even at a low speed by integrally forming a holding section which holds an air-core coil and a bearing section which is put on a fixed shaft formed at a position deviated from the center of gravity of an eccentric frame with the frame. SOLUTION: Since an eccentric frame 1 is made of a sintered material and a holding section 1b and a bearing section 1a are integrally formed in one body, it becomes unnecessary to manufacture a rotor and a bearing as separate parts and the number of parts can be reduced. Since the bearing section 1a is not assembled to the frame 1, the accuracy of the bearing section 1a as a single parts, such as the squareness of the inside diameter of the section 1a to the horizontal plane of the frame 1, etc., can be secured easily and the section 1a can be assembled with sufficiently high coaxiality. When the frame 1 rotates, therefore, a rotor does no run out, but smoothly rotates. In addition, since the frame 1 is made, of the sintered material, a large vibration effect can be obtained from a vibrating motor even when the motor is rotated at a low speed.
